ChemStar belt-driven vacuum pumps are designed to tolerate harsh chemical contamination. Vital pump parts are corrosion resistant.  The large oil reservoir with PTFE surfaces dilutes contamination and the low pump rotational speed lessens friction to reduce operating temperature and chemical effects. PTFE surfaces, fluorocarbon gaskest and seals, nitrogen purge to cool and degas oil. ChemStar pumps come with Welch Gold oil, a synthetic pump fluid designed to minimized effects of chemical contaminants.

Applications: Freeze dryers, vacuum ovens, schlenk lines, HVAC service, distill high boiling point compounds, degassing.
